ispDOWNLOAD Cable TM
Download Cable for In-System Programming of the ispLSI®, ispGAL®, ispGDX™ and ispGDS™ Device Families the parallel port of a PC. With In-System Programmability, hardware functions can be programmed and modified in real-time on the system board to give additional product features, shorten system design and debug cycle time, enhance product manufacturability and simplify field upgrades. After completion of the logic design and creation of a JEDEC file by a logic compiler such as ispDS™, the ispDS+™ Fitter or ispGDS Compiler software, Lattice’s ISP Daisy Chain Download software programs devices on the end-product PC board by generating programming signals directly from the parallel port of a PC which then pass through the ispDOWNLOAD Cable to the device. With this cable and a connector on the PC board, no additional components are required for programming. The ISP Daisy Chain Download software automatically generates the appropriate ISP command, programming address and data from the JEDEC fuse map information. ISP Daisy Chain Download software is included with all Lattice ispDS and ispDS+ Fitter products.

5 ISP Device
The ispDOWNLOAD cable assembly provides an interface between the ISP signals from the serial interface adapter and the target ISP system. The features of the ispDOWNLOAD cable assembly include:
ispDOWNLOAD Cable for Sun Workstation The ispDOWNLOAD Cable for the Sun Workstation provides a quick and easy means for programming all Lattice ISP devices from a Sun Workstation. Setting up the workstation ispDOWNLOAD cable is as simple as connecting the serial interface adapter to the RS-232 port of the workstation and connecting the ispDOWNLOAD cable assembly to the target ISP system.
• Six feet of eight-conductor flat cable with an RJ-45 connector on one end an an eight-position female header assembly on the other end • RJ-45 connector for reliable and easy interfacing to the serial interface adapter
The serial interface adapter contains an embedded controller that handles programming commands from the host workstation to the target system and processes them for proper ISP operation. Additional features of the serial interface adapter include:
• Eight-position female header connector with .10” pin spacing for quick and low-cost interfacing to ISP target systems with a mating header pin strip. Keying is provided on the header connector for proper interfacing orientation
• Automatic baud rate detection for 300 baud to 115,200 baud operations
• Header connector assembly with super flexible wiring for durability
• Operational at supply voltages of 3.3V or 5V • Standard Lattice ISP programming interface and ispJTAG™ interface (IEEE 1149.1) support • RJ-45 interface jack for easy ISP cable assembly replacement • Compact size and low power requirements • Easy interface to the Lattice isp Engineering Kit Model 100 for single ispLSI device programming 2
